Question

the point of intersection of the medians of a triangle is called the __.incentercentroidorthocenter circumference18. choose the correct answer.the __ will lie at the vertex of the right angle in a right triangle.orthocenterincentercircumcentercentroid

Explanation:

• For the first question: The centroid is defined as the point of intersection of the medians of a triangle. The in - center is the intersection of angle bisectors, the ortho - center is the intersection of altitudes, and circumference is related to the perimeter of a circle (not relevant here).
• For the second question: In a right - triangle, the ortho - center (the intersection of altitudes) lies at the vertex of the right angle. The in - center is located inside the triangle (not at the right - angle vertex), the circum - center is at the mid - point of the hypotenuse, and the centroid is located inside the triangle (not at the right - angle vertex).

Answer:

1. B. centroid
2. A. orthocenter
